🏰 Stephon Castle Rookie of the Year odds (-500)
We've been calling attention to Castle's value since he was trading at +2000 odds early in the year.
San Antonio being all but out of contention because of the Victor Wembanyama injury has led to the uptick in minutes for the rookie that some expected. Castle has impressed with a high-scoring output during his fluctuating minutes, bringing his average to 14.2 points per game on the year in 26 minutes per game.

🔴 Zaccharie Risacher Rookie of the Year odds (+850)
Risacher was the No. 1 pick in last year's NBA draft, so it's no surprise he was one of the early favorites to win the award. However, like much of the unspectacular rookie class, he struggled to get acclimated with the Association. The 19-year-old has now grown into his role over the past couple months, enjoying his best scoring output of the season.
Atlanta's newest star's 16.3 points per game in March were the highest of his career to date, and he's now up to 12.4 PPG overall. However, Risacher's emergence seemingly happened too late, with Castle an overwhelming favorite to win Rookie of the Year.
If Risacher wants to make an extremely late push, he'll need to build on his career-best 36-point outing against the Milwaukee Bucks on March 30. A $10 winning wager on the reigning first overall pick would return $85 at our best sports betting apps.

📖 How to read NBA Rookie of the Year odds
Reading NBA Rookie of the Year (ROY) odds is simple once you know the basics. Odds are typically presented in a format like +300 or -150. Positive odds (e.g., +300) indicate how much profit you'd make on a $100 bet. For instance, a $100 bet at +300 odds would win you $300, plus your initial $100 stake, totaling $400. Negative odds (e.g., -150) show how much you need to bet to win $100. So, a $150 bet at -150 odds would win you $100, plus your $150 stake, totaling $250.
Odds also reflect the probability of an outcome. Lower odds (e.g., +100) suggest a higher probability of the player winning, while higher odds (e.g., +1000) indicate a lower probability. Sportsbooks adjust these odds based on factors like player performance, injuries, and betting patterns.
For example, if Rookie A has +200 odds and Rookie B has +500 odds, Rookie A is considered more likely to win. If you bet $100 on Rookie A and they win, you'd get $300 back ($200 profit + $100 stake). Reading and understanding these odds helps you make informed betting decisions.
